I know exactly where that picture was taken. Wife and I were on Maui for 2 weeks in '08 (second time there) looking for possible retirement property ... found out all I could afford was a spot to stand on.

We dove several times - hearing the humpbacks while underwater is a song that shall forever reverberate in my soul. Diving with Bertha off Kona on the Big Island was another memory permanently engraved in me. She played with us for over a half hour (I think she loved my camera lites) ... that is my wife that she gracefully "hugs" in the fly-by's

You must be storing in the sun when furled? That is clearly UV damage by looking at the color change / fade along the foot and leech.

If you look a big sailboats who have furling jibs, they often have a wide strip of UV stable cloth in these faded areas. A sailmaker would be able to do that for you. Especially if leaving the mast up for long periods. Then when furled, it's like having a sail cover on.

We do recommend storing in the bag and out of the sun though.

Do you have a drawing of the AI sail with dimensions available that I might email to our local sailmaker, to get a quote for adding the UV cloth?
